        lensfunpy is an easy-to-use Python wrapper for the `lensfun library <http://lensfun.berlios.de>`_.
        
        Sample code
        -----------
        
        How to find cameras and lenses:
        
        .. code-block:: python
        
            import lensfun
        
            camMaker = 'NIKON CORPORATION'
            camModel = 'NIKON D3S'
            lensMaker = 'Nikon'
            lensModel = 'Nikkor 28mm f/2.8D AF'
        
            db = lensfun.Database()
            cam = db.findCameras(camMaker, camModel)[0]
            lens = db.findLenses(cam, lensMaker, lensModel)[0]
            
            print cam
            print lens
        
        How to correct lens distortion:
        
        .. code-block:: python
        
            import cv2 # OpenCV library
            
            focalLength = 28.0
            aperture = 1.4
            distance = 10
            imagePath = '/path/to/image.tiff'
            undistortedImagePath = '/path/to/image_undist.tiff'
            
            im = cv2.imread(imagePath)
            height, width = im.shape[0], im.shape[1]
            
            mod = lensfun.Modifier(lens, cam.CropFactor, width, height)
            mod.initialize(focalLength, aperture, distance)
            
            undistCoords = mod.applyGeometryDistortion()
            imUndistorted = cv2.remap(im, undistCoords, None, cv.INTER_LANCZOS4)
            cv2.imwrite(undistortedImagePath, imUndistorted)
            
        Installation
        ------------
        
        You need to have the `lensfun library <http://lensfun.berlios.de>`_ installed to use this wrapper.
        
        On Ubuntu, you can get (an outdated) version with:
        sudo apt-get install liblensfun0 liblensfun-dev
